How to service the wear compensator of clutch actuator презентация

How to initialize or rewind the wear compensator (Without reassembling actuator motor)?
1. Jig and tool for wear compensator
※ Purpose of initializing/rewinding the wear compensator
- It is necessary to initialize/rewind the wear compensator when replacing the double clutch or clutch actuator with a new one.
▶ In case of the 7-speed DCT, wear compensator is included in the clutch actuator.

2. Installation diagram of clutch actuator on the wear compensator jig

⑦ Stand the clutch actuator vertically with installed to the base jig.
- After standing the clutch actuator vertically, remove the hooks
and levers from the output rods.

⑩ Rotate the tool clockwise as desired for shortening the
output rod length (B) to the previous output rod length (L).
- Rotate the tool counterclockwise when increasing (+) the
output rod length.
- Rotate the tool clockwise when shortening (-) the
output rod length.

⑮ Install the new clutch actuator to DCT and then reassemble the
double clutch.
- Rewinding wear compensator is completed
- Reinstall the DCT to a vehicle and then carry out the
manual DCT learning using G-Scan or GDS-Mobile

■ Calculation of the number of turns for wear compensator tool
Calculating formula for the number of turns and rotating direction (+/-)
: (Length after adjustment - Length before adjustment)/Length change
per 1 revolution
[When rewinding wear compensator]
= (Rod length of removed clutch actuator L - Rod length B of new clutch actuator )/0.25mm
※ Rotate tool counterclockwise to increase (+) the rod length.
Rotate tool clockwise to shorten (-) the rod length.
[Rewinding case of output rod length]
1) Actually measured output rod length (L1, L2) of removed clutch actuator
Rod length for odd gear L1 = 70.0
Rod length for even gear L2 = 68.0
2) Actually measured output rod length (B1, B2) of new clutch actuator
B1 = B2 = 73.0 mm (Medium 7-speed DCT)
3) It is necessary to rewind the output rod length of new clutch actuator
because the rod length (B1, B2) is different to the rod length (L1, L2).
- L1 (70.0) ≠ B1 (73.0) - L2 (68.0) ≠ B2 (73.0)
4) The number of turns for wear compensator tool
(L1–B1)/0.25=(70.0-73.0)/0.25 = -3.0/0.25= -12 revolutions
(L2–B2)/0.25=(68.0-73.0)/0.25 = -5.0/0.25= -20 revolutions
